Retrotransposons and Telomeres
Abstract Transposable elements (TEs) comprise a significant part of eukaryotic genomes being a major source of genome instability and mutagenesis. Cellular defense systems suppress the TE expansion at all stages of their life cycle. Piwi proteins and Piwi-interacting RNAs (piRNAs) are key elements of the anti-transposon

Condensin II subunit dCAP-D3 restricts retrotransposon mobilization in Drosophila somatic cells. [PDF]
Retrotransposon sequences are positioned throughout the genome of almost every eukaryote that has been sequenced. As mobilization of these elements can have detrimental effects on the transcriptional regulation and stability of an organism's genome, most

The retrotransposon R2 maintains Drosophila ribosomal DNA repeats
Ribosomal DNA (rDNA) loci contain the hundreds of tandemly repeated copies of ribosomal RNA genes needed to support cellular viability. This repetitiveness makes it highly susceptible to copy number (CN) loss, threatening multi-generational maintenance ...

Advances in the pathogenesis of Rett syndrome using cell models
Most Rett syndrome (RTT) patients are affected by the MECP2 gene mutations. And the mutations of MECP2 have wide effects on different cell types of nervous system, including neurons, astrocytes, oligodendrocytes and microglia, which always combined together to lead to abnormalities in the whole neural network.

Abstract Premise Although several software packages are available for genotyping insertion/deletion (indel) polymorphisms in genomes using next‐generation sequencing data, simultaneously calling indel genotypes across many individuals for use in genetic mapping remains challenging. Methods and Results We present an integrated pipeline, InDelGT, for the

Microarray analysis of LTR retrotransposon silencing identifies Hdac1 as a regulator of retrotransposon expression in mouse embryonic stem cells. [PDF]
Retrotransposons are highly prevalent in mammalian genomes due to their ability to amplify in pluripotent cells or developing germ cells. Host mechanisms that silence retrotransposons in germ cells and pluripotent cells are important for limiting the ...

Endosymbiotic ratchet accelerates divergence after organelle origin
Primary endosymbiosis gave rise to mitochondria and plastids. The proximate impacts of organelle origin on lineage evolution have not been addressed at the population level. Using data from the photosynthetic amoeba Paulinella, we hypothesize that primary endosymbiosis accelerates lineage divergence, a process we refer to as the endosymbiotic ratchet ...

Abstract Clustered regularly interspaced short palindromic repeats‐associated protein (CRISPR/Cas9), an adaptive microbial immune system, has been exploited as a robust, accurate, efficient and programmable method for genome targeting and editing. This innovative and revolutionary technique can play a significant role in animal modeling, in vivo genome

This study investigated the effects of retrotransposon movements on the regeneration of 15- and 30-day-old leaves and roots of four different rice varieties grown in tissue culture medium at different salt concentrations (0, 50, 100, and 200 mmol/L) by ...
